Some argue that genre is the lens that focuses the writer’s attention on one or the other. A whodunit, they suggest, is more plot-driven than a European art film that concentrates more on character.
But need this be absolutely the case? Would concentrating on both not serve to enrich any story, regardless of its genre? Especially because plot and character are so deeply interwoven, that you can’t invoke one without invoking the other?
How character affects plot
The following analogy is helpful: Plot is to character as a beam of light is to a prism passing through it. The prism refracts the flow of the plot.
Slap a Nazi officer on the cheek and you’re likely to get shot. Slap one of the twelve disciples instead, and he may well offer you the other cheek. Both reactions, which might be pivotal turns in the story, are influenced by the personality, beliefs, and ideology of the characters involved.
In the film Gladiator, for example, can you imagine Maximus failing to fight back against the Emperor who has poisoned him, then stabbed him with his sword in one-to-one combat in the arena?
Much more fitting is that Maximus pull the Emperor’s sword from his belly with his bare hands and use it to stab the Emperor to death with it.
This action is only possible because of who Maximus is, a man of immense will and strength who is determined to revenge the death of his family and save Rome from being ruled by a madman. His action is in keeping with his character.
And so it should be with any character whatever the magnitude of his actions, since, in terms of narrative construction, actions are nothing more than responses to challenges and opportunities presented to the characters of a story.
The plot of a story is directed through the prism of character.
